Study summary

The prognosis for patients with localized pancreatic adenocarcinoma who are not surgical candidates is poor. Patients characterized as having "borderline resectable" disease treated with preoperative chemo-radiotherapy fair somewhat better - although many of these patients are not converted to resectability. It may be argued that intensification of local and regional therapy might 1.) Increase the share of patients able to undergo curative surgery and 2.) Improve the local disease control interval and extend survival for patients who remain unresectable. Therefore, the purpose of this research study is to determine if an increase in the number of surgical resection pancreatic adenocarcinoma is higher than historical data by using a combined treatment of proton radiation with capecitabine (oral chemotherapy).

Read the detailed description

Participants as part of this research study will receive Proton radiation over 6 weeks with oral chemotherapy (capecitabine) only taken on radiation days.

In addition, If surgery is an option, then surgical resection will be performed at least 8 weeks after treatment with radiation and chemotherapy.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • proven unresectable adenocarcinoma of the pancreas.
  • Have either unresectable, borderline resectable or medically inoperable carcinoma of the pancreas, or refusing surgery.
  • A biliary obstruction is able to participate as long as a drainage tube is in place prior to starting treatment with Proton radiation,
  • Participants of child-producing potential must be willing to use while on treatment and for at least 12 months thereafter.
  • Required pretreatment laboratory parameters:

    • Absolute granulocyte count (AGC/ANC) ≥ 1.8 thou/mm3
    • count ≥ 100,000/mm3
    • \< 2 mg/dl
    • /SGPT \< 3x
    • Creatinine \< 3 mg/dl

Exclusion criteria

Exclusion Criteria:

  • Evidence of distant .
  • Prior surgical resection.
  • Previous history of invasive (except non-melanoma skin cancer and low to intermediate risk prostate cancer) unless the participant has been disease free for 5 years prior to registration.
  • Active or untreated infection,
  • Pregnant or breastfeeding women or subjects of child producing potential not willing to use medically acceptable while on treatment and for at least 12 months thereafter.
  • Previous Radiation to the abdomen.
Terms in these criteria, in plain language(8)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Biopsy and archival tissue

A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.

Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Platelets

Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.

Bilirubin

A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.

Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.

ALT and AST (liver enzymes)

Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.

Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.

ULN (upper limit of normal)

The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.

“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.

Metastases

Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Study arms

  • Experimental
    Proton Radiation with capecitabine

    The following will be performed in this group: Proton Radiation Therapy with concomitant oral chemotherapy, capecitabine taken on radiation treatment days for 6 weeks. A surgical resection will be performed between 8 and 16 weeks if radiographic studies suggest operability.

    Radiation: Proton Radiation · Drug: Capecitabine · Procedure: Surgical resection

Interventions

  • RadiationProton Radiation

    Proton Radiation 40.50 Gy relative biological effectiveness (RBE) in 18 fractions to gross disease and elective nodal volume followed by a 22.50 Gy (RBE) in 10 fraction boost to gross disease. Total dose 63 Gy (RBE) in 28 fractions over 6 weeks.

    Also known as: Proton Beam Radiation

  • Concomitant oral chemotherapy, capecitabine 1000mg by mouth twice daily, 5 days a week (M-F) on radiation days only.

    Also known as: Xeloda

  • ProcedureSurgical resection

    Surgery between 8 and 16 weeks of radiotherapy completion if radiographic studies suggest operability.

What researchers measure

Primary outcomes

  1. Overall survival at 12 months after radiation therapy

    The trial is designed to allow detection of an improvement in the 12 month overall survival rate to 75% compared to the expected historical rate of 50%.

    Time frame: Approximately 12 months after radiation therapy.

Secondary outcomes

  1. Surgical resection rate.

    Increase share of marginally resectable and unresectable patients being converted to resectable.

    Time frame: 3 months following the completion of radiation therapy.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
